Mechanical 20 Minute Timer

Get Your Exclusive Chronograph

If you are fascinated with regular watches and stopwatches, then this construction kit is perfect for you as it brings one of the most popular timekeeping devices of today – the chronograph, which is well-known for recording time accurately. Now, you get to build your very own chronograph and proudly show it off to friends. 

  • Looks beautiful and unique – makes a fine accessory for your workstation or desk at home. You can even display it in the living room, as it can be used to impart a decorative touch too as a vintage element.
  • The mechanical device can be set for any time ranging from 1 to 20 minutes. It is really easy to operate due to the wind up alarm system that sets off the alarm after the time runs out.
  • The chronograph timer has a highly efficient roller pendulum and amplitude adjustment system on the back wall.
  • The timer can be powered using plain office rubber bands – this is a common feature in most models under the UGEARS label.
  • It doesn’t take much time to put together – you can rope in a friend or build it with your child.

The model kit is an excellent gift for a wide age group – all they need is a passion for creating things from scratch. Being associated with the UGEARs brand, you can rest assured the product is of premium quality and will last for a long time. This model has been tweaked quite a few times to create an ideal version of this exquisite gadget. Moreover, you don’t have to deal with irritating, sticky fingers as the parts are designed for self-assembly sans any kind of glue – this characteristic is what makes our patented inventions even more special.

Models assembly tips


  • If you hold the board with its front side directed to you, it is better to remove the parts by pulling them. In this case, if a burr is pulled together with a part, it will make a pit in the board, not in the part. The best solution is to incise the hangers with a knife;
  • If you have difficulties in inserting a toothpick in the assembled gearwheel, rub the toothpick with a candle;
  • You may also lubricate all the projecting axes of the gearwheels before installing them on the frame. In this case the friction during rotation will be minimal;
  • However, do not lubricate the parts of pendulum connection with a candle – two projecting sticks in the tractor or timer. In this case the pendulum will not swing but skid;
  • Try to remove big burrs on the gearwheels, if any. The motion of some models is very delicate, and they may hinder it;
  •  If any gearwheel creaks or squeaks, lubricate it with a regular candle, paraffin or wax. If the plywood edge is too resinous and some teeth tend to seize, which happens quite rarely, lubricate the gearwheel in the same manner;
